Highway 550 Montrose, Co. to 64 in New Mexico

Just spent a week during the July 4th holiday in and around Durango and US550 posed no issues in CO or NM, although there is some minor road construction in a couple of areas.

550 from Ouray to Durango is aka the Million Dollar Highway. It is high mountain driving with lots of steep inclines and descents, switchbacks, and steep dropoffs without guard rails. Not for the faint of heart, but certainly doable if you're comfortable with that type of driving. The scenery is spectacular! All kinds of rigs, as well as tractor/trailers, traverse it daily, weather permitting.

Enter "million dollar highway" into the search for lots more information.

We drive that road every year in our signature rig. Getting ready to head up there next week. Like the above poster said, it is not for the faint of heart or anyone afraid of heights. Just go slow and watch the road, let someone else take pictures out the windshield and look at them later. The section between Ouray and Durango is breathtaking. Drive safe and have fun. Here is a sample.

I love this road. That said, I have only done it on a motorcycle
Have a blast..

Have done it with our rig and toad, so yes it is doable with a big rig. As previous posters have said, if you are not comfortable with serious mountain driving, then stay off the section from Ouray to Silverton. The 2 pictures by jnjnkatiebug are tame if you consider the first 5 miles out of Ouray.

Montrose to Ouray is a piece of cake - mostly flat.

Ouray to Durango is as described above. We have done it many times and are comfortable with it but it all depends on your comfort level for real mountain driving. Your MH is certainly capable of doing it. You just go slow as everyone else does. Semi trucks drive this route.

Actually heading south as you would be doing seems a lot easier because you're against the mountains, not on the edge. The major part is from Ouray to Silverton then it gets much better. :)

Silverton is an awesome place to spend a night or two - or more. There are some wonderful 4-wheeling drives of all abilities right from town. It's 4-wheeling at its best. We've been on all of them over the years in our '04 Liberty. We boondock there but if you stay in one of the RV parks it would be full of 4-wheelers. Get to talking to some of them and they most likely would let you tag along on one of their rides. Its more fun with someone else. It's one of our favorite places.

From Durango south it's easy.

Another route you might consider which is milder is from Ridgeway picking up Hwy 145 through Telluride and down to Cortez. It's still mountain but of a more gentle kind! But then you'd miss Silverton unless you drive back up just in your Jeep from Durango. Have a good trip!
